The European Securities and Markets Authority (ESMA) has developed draft Implementing Technical Standards specifying main indices and recognised exchanges as required under Paragraph 8 of Article 197 of Regulation (EU) 575/2013 (Capital Requirements Regulation).
These have now been submitted to the European Commission submitted for endorsement of the draft ITS.It has 3 months to make this decision.

The Final Report contains the draft Regulatory Technical Standard (RTS) on situations which require the publication of a supplement to the prospectus which ESMA is required to submit to the European Commission by 1 January 2014 in accordance with Article 16(3) of the Prospectus Directive. The Report furthermore includes a summary of the main responses received to ESMA’s Consultation Paper which was published in March 2013.
The draft RTS sets out nine situations which are always considered to be significant in the context of securities issuance and where a supplement to the prospectus will always be required. Other situations would require a case-by-case assessment.
